What are the <tr>, <th>, and <td> tags used for in HTML?

The tags <tr>, <th>, and <td> are used to create tables in HTML.

• <tr> (table row) — defines a row in the table.
• <th> (table header) — defines a header cell in a row. Usually, the text in such a cell is displayed in bold and centered.
• <td> (table data) — defines a data cell in a row. Contains the main information in the table.

    <th>Header 1</th>

  </tr>
  <tr>
    <td>Data 1</td>
    <td>Data 2</td>
  </tr>
